6, a fuel gas boiler room boiler should correspond to a chimney, when required by the conditions a boiler flue or chimney common to several units, each boiler should be ventilated suction force balance.
7, when the flue arrangement provided the necessary thermal and environmental measuring point measuring point in place. Single rated evaporation amount is equal to 20t / h or single thermal rating of greater than or equal 14MW oil-fired boiler, a fixed continuous monitoring must be installed in the flue gas dust, SO2 emission concentration instrument.
8, in the flue gas gathering place easily and when many boilers a share or a total chimney flue shall be fitted with explosion-proof door on the flue after each fuel gas-fired boiler, the location of the vent should be conducive to relief, It should be provided without jeopardizing personnel safety and proper position before turning, when explosive gas may endanger the safety of the operator that should be installed on the guide tube explosion relief means.
9, for some long flue boiler room, they should be accounted for resistance, select the appropriate blower, Fan (when there is draft fan), to ensure the smooth flow of exhaust.
10, the chimney should be considered appropriate anti-corrosion measures, chimney flue gas outlet temperature is preferably above the dew point of the flue gas temperature of 15 deg.] C; when the exhaust gas temperature is lower than the dew point temperature of flue gas, the flue gas should take effective measures to prevent the intrusion.
Boiler welding, Why a T-joint, do not use pull side welding? The connection 3.7.2T-junction "technology to monitor the 5 ton per hour boiler in textile industry in haiphong safety regulations" TSGG0001-2012: not greater than the rated working pressure of 2.5MPa and a horizontal tubular boiler combustion boilers, flue gas temperature of the working environment is less than the pressure receiving member 600 ℃ connection, when the following conditions may be employed butt T-junction using the connection but not lap joint: 1, the weld joint type using full penetration, and the machined groove; 2, horizontal boiler combustion boiler shell, the furnace tube plate and connected to the cylinder insert structure should be used; 3, T-shaped joint connection site weld thickness is not less than the wall thickness of the tube plate, and which can be sealed back seam welded portion should seal welded, not welding portion can be sealed welding backing should be used, and to ensure penetration; 4, the weld joints connecting portion of the T-shaped ultrasonic testing according NB / T47013 "nondestructive Testing pressure equipment" the relevant requirements.
March 22 to 23, Ganzhou City, Jiangxi Province Bureau of Quality Supervision established party leadership team, the progress of the 2018 phase-out of coal-fired 5 ton per hour boiler in textile industry in haiphongs to conduct random work. Leading group led by Liu Ping, deputy director of Ganzhou City, Municipal Quality Supervision Bureau, the Municipal Industry and Information Commission, the Municipal Environmental Protection Bureau and the Municipal Development and Reform Commission composed of four departments jointly checks group within Xinfeng County of Ganzhou City, Nankang District, Jiangxi counties and carried out spot checks Yudu County coal-fired boilers working-out of a total of 17 companies.
Sampling results show that 17 companies, more than 10 companies to complete phase-out of coal-fired boilers, the other seven unfinished business executives also said that this year will be to complete the rectification work before December 20.
In this sampling event, checks the group also proposed rectification direction of the coal-fired boilers for local authorities: by strengthening the policy advocacy, strengthening inter-site inspectors guidance and strengthen departmental interaction, the three parties work together to ensure the timely completion of this non-compliance within Ganzhou coal-fired boiler out of the task.
The difference between the dangers of silica and 5 ton per hour boiler in textile industry in haiphong pressure and atmospheric pressure: shell boiler in the boiler, which is a kind of boiler? On boilers, pressure and pressure, what is the difference? And, if the boiler is too high in silica content, so, what adverse effects there? These issues are on the boiler, and also the front yet, so below, to give the corresponding answer it, and so that we learn through to clear. 1. boiler shell boiler, which is a kind of boiler? Shell boiler in the boiler, we can call it a fire-tube boiler. A boiler that, if specifically, it is as follows: in the boiler, which uses a two-layer structure is jacketed, is outside the boiler shell, there is a furnace. The medium of the water, is between the outer cylinder and inner cylinder. Further, the inner tube thereof, is a combustion chamber. And flue gas generated in the boiler, is the result of the inner cylinder, instead of the outer cylinder. Therefore, which boiler shell is subjected to internal pressure, furnace, it is subjected to external pressure.
